ELECTRODE DEVICE FOR HIGH-FREQUENCY APPARATUS.

Specification of Letters Patent.

Patented Dec. 15, 19141.

Original application filed November 21. 1910. Serial No. 593.365. Divided and this application filed October To all teliolu- 2'1 may (One/I'm Be it known that l. \Ynmuu l)t'l-ll,ll-.lt. wiose residenee is No. lit North Fourth street, Brooklyn. New York. hare invented a Certain new and usel'ul lmprovenu-nt in Elect-rode l eviees tor lligh-lh-euueuev .\pparatns. and do here y derlare that the tollowing, is a full, elear. and e.\'aet deseriptioir thereof.

The object of m v invention has been to pro\ide an eleetrode deiiee 'l'or high l reqneneaapparatus. whieh shall be simple. reliable, eapable of being: easily IP-Sttll'lttl-tlllll 'apahle of using a h \'droearbon atmosphere. and to sueh ends m v invention eon sists in the eleetrode devire for high trequehcy' apparatus hereinafter spe ilied.

In the aeompairVlng drawings the lite are is a vertieaLseetional \'ie\\ of the deviee.

I have illustrated that form ol m v deviee which is the best orm known to me. but it is to be regarded as t vpieal only of mair'v possible embodim nts.

The form chosen tor illustration (romprises a hollow easing 1 of any suitable eon ductive material. and an eleetrode 2 within Said hollow eleetrode. The electrode 2 is clamped in a Sleeve 3. as by a serew l. The sleeve is secured -on a rod :1. that is mounted in a threaded sleeve (3a the latter being threaded into a bushing T. The bushing: consists of a dish 8. a sleeve J and a disk It serewed on the sleeve, the said disks elam r in; between them insulating material ll.

whieh is plaeed on opposite sides ol' and 4 against a dish l. serewed to the open end of the hollow eleetrode. A hand-wheel It is seeured to the sleeve (3, so that the latter may beadjnsted up and down in the bushing. A collar 13 is seeured to the upper end of the rod l, and a spring 15 is interposed between saidwollar and the 'ha'nd-wheel, so that it tends to draw the sleeve 3 against the lower end of the sleeve ti. The low er eleetrode 16 is preferably made separate from the eup l Serial N0. 655.725.

so that it run be readily renewed. By this arrangement. the eleetrode 9 can be adjusted.

the proper distauee from the lower electrode lt'i. lrv turning the haml-wheel. and the arc (all then be started b v simply depressing the rod 5. l'pou releasing the said rod, the spring will raise the eleetrode so that the proper degree or" separation will automatieall v oe ur between the electrodes. The h0llow eleetrode is provided with a pipe 17, through whit-h gas may he introduced 01 a mixture ot gas and air. and with an escape 1H for the prodnets ot' eombnstion. thus enahlin; an atmosphere of h \'dro-earbon or other gas to be provided. in whiell ahigh t'reuueuev are may be formed.

Patent Number 1.023. 35. issued Am. 1(3, 1012.

l elaim:

in a deviee ot' the eharaeter deseribed, an eleetrode in the t'orm of a hollow enp and having a removable pieee in the elosed end thereof. a bush ng mounted in the open end of said eup and insulated therefrom. a

sleeve provided with a hand wheel and threaded in said insulated bushing. a rod provided with a eollar and slidabtv mounted in said slee\e. a eoil spring mounted on said rod between said hand wheel and said (01- lar. a sleeve mounted on the lower end of said rod and adapted to limit. the upward movement ot'said rod. andan eleetrode mounted in said last-named l(t\t3 with its sparking end opposite said removable pieee in the ('losed end of said tllp.

in testimony that l elaim the foregoing I have hereunto set my hand.
